It really isn't the best way to do things and has been the source of a few jarring moments in otherwise great game flow. I've started making quick audio notes after sessions so that I can have a quick refresher before the session begins.
For the sake of building some enthusiasm, honing my craft, and having a little fun with my friends, it occurred to me that I could turn these into a podcast with a tiny and very specific audience. Although, once it is in full swing it might be interesting to other players who want to see how those older 1970s style rules and 1:1 time play out in an actual game.
Once the 5-10 minutes of audio notes are recorded, I also realized that I could also record some of the lore about the campaign setting in a fun delivery package that helps me avoid lore dumps in the game. "Here's 5 minutes of stuff you might want to know and might be interesting, but isn't game critical - and you can skip!" seems like a winning formula. Especially as it is as much about me as them.
If you are curious, here are my first to proper session versions of the micro-podcast:
